ALBERT L. GOODENOW, 0F UTICA, NEW YORK.

FURNACE-REGULATOR.

To all whom it may concern:

Be it known that I, ALBERT L. GooDENow, a citizen of the United States,residing at 136 Brinckerhoff avenue, Utica, in the county of Oneida andState of New York, have invented certain new and useful Improvements inFurnace-Regulators, of which the following is a specification, referencebeing had therein to the accompanying drawing.

My invention relates to an improved furnace regulator, and I declarethat the following is a full, clear, concise and exact descriptionthereof, suflicient to enable one skilled in the art to make and use thesame, reference being had to the accompanying drawing in which likereference characters refer to like parts throughout.

The invention consists in the construction and combination of theseveral cooperating and co-acting members whereby the air draft and thecheck draft of a furnace may be operated from different positions orstations to open either and close the other and maintain them in suchposition, or in intermediate positions of either or both of them,weights being provided which may be adjusted or graduated to theconditions involved in the location of the station to which the chainsrun and the amount of friction and the weight of the several connectingmembers.

Other features of the invention will appear herein.

In the drawings Figure 1 is a front view of the device with parts brokenaway. Fig. 2 is a front view of a portion of the device showing thesupport of the chain, the face plate being removed, but a part of itshown in section. Fig. 3 is a reverse view of the central disk. Fig. 4:is a cross section taken on line 4-4: of Fig. 1.

Referring to the figures in detail, 1 represents a base apertured formounting the device on the wall and having a central stud 2.

3 is a disk centrally bored as at 4 and adapted to be revolubly mountedon the stud 2. The disk 3 is of the form as inclicated in Fig. 4 and ata given point on the periphery is mounted an eye 5 to which areconnected the oppositely extended chains 6 and 7. At a given point onthe face of the disk is the indicator point 8. The peripheral wall ofthis disk is such as to allow free movement of the chains withoutbinding on the base 1 or the top, to be described. In the hollow of thedisk, at suitable points, are

of the disk 3 with the face of the disk flush or substantially flushwith the face of the cover 12. The cover is suitably supported on thebase by bolts 14 in holes 15 and thus holds the disk 3. Its faceadjacent to the edge of the disk 3 is marked with numerals as indicatedin Fig. 1 to indicate the position of the draft and check. In Fig. 2 areshown broken portions of the vertical walls of the cover indicated by 16and 17 showing how the end of the vertical wall is formed to provide afree running surface for the chains.

It will be observed by reference to Fig. 2 that there is a swing of thedisk in either direction, to operate the check or draft, equal to thedistance from the point where the eye is shown to the point where theeye will be when drawn downward to the lowest possible point and whichmovement will open one door to the limit under such arrangement as isshown. The arrangement may be different as will be evident by supposingthat the disk is turned, in assembling the device, so that the eye is atthe bot-tom and one chain runs from it, without slack, to one closuremember which is in closed posi tion, the other chain being carriedaround the disk. It will be seen that by revolving the disk it can makesubstantially a complete revolution and the lift or fall of each chainwill be substantially the circumference of the disk and about twice asmuch as with the former arrangement.

In order that the weight of the doors and the chain connectin theretomay be equalized and friction al owed for, I provide at some suitableposition means for efiecting the counterbalance. Such means is hereshown, in Fig. 1, by weights 20 and 21 which consist of a base portionwith shanks 22 and 23 in each on which are supported removable weights24 and 25 which may be added or removed to such extent as may benecessary. At 30 and 31 are shown grips of any suitable form bearing alegend appropriate to the function of the chain to which it isconnected, as for instance to indicate which chain to use to operate thecheck draft and which to operate the front draft.

Having described my invention, what I claim as new and desire to secureby Letters Patent is:

l. A furnace regulator comprising a fixed base, a chain carrying diskrevolubly mounted thereon having its edge offset to provide a ridingsurface for regulating chains or the like, said chains or the like, acover having a face portion of ring-like form and a peripheral wallvertical to the face, the said face and the opposite base and theperipheral wall and the ofiset edge of the disk forming a chamberwherein the chains are confined in their travel, the peripheral wall ofthe cover being cut out to provide an opening for the passage of thechain, the terminal edges of said wall forming bearing and guidingsurfaces for the chains, substantially as described.

2. A furnace regulator having a fixed base, a disk revolubly mountedthereon, the disk having ball-cups opening against the base and ballstherein bearing on the base, chains carried on the disk, the same havinga peripheral wall for the support of the chains, and a cover having aperipheral wall inclosing the disk and the chains thereon but having apassage the-rethrough for the chains, the passage being of less extentthan the diameter of the disk whereby either chain may be given anextent of movement substantially equal to the circumference of the disk,substantially as described.

8. A device of the character described consisting of a revoluble diskwith its edge upset in the form of a peripheral wall, chains carried onthe wall of said disk, oppositely disposed abutments having acomparatively small space between them for the passage of the chainswhereby the revolution of the disk is effective to shift the chains adistance substantially equal to the circumference of the disk andadjustable Weighting members on the chains and forming a part thereof,the same comprising a shank connected to the links of each chain and abase on the shank adapted to support added weights, substantially asdescribed.

4. A furnace regulator consisting of a plurality of chains or the likecarried from the furnace drafts to a series of stations and a revolubledisk at the farthermost of said stations, the chains being attachedthereto, means forming part of the chains adapted to receive a givennumber of weights to efiect proper counterbalance according to theweight of the draft to be operated and of the chains and means guidingthe chains in comparative proximity to the disk whereby the revolutionof the disk shifts the chains an amount substantially equal to thecircumference of the disk, substantially as described.

5. A furnace regulator having a fixed base with a central stud, a diskrevolubly mounted on the base and having its edge upset in the form ofchain supporting walls, antifriction balls and means supporting saidantifriction balls between the base and the disk, a cover overlappingthe disk and adapted to be secured to the base, the cover having wallsresting on the base and cut away for the passage of chains, and chainsmounted on the disk adapted by revolution of the disk to operate thefurnace members connected therewith, substantially as described.

In testimony whereof I have afiixed my signature in presence of twowitnesses.
